See the world as it really is. Most world maps stretch the far north and south, so Greenland looks as big as Africa. Equal Earth uses an equal-area projection: every country appears at its true relative size. Explore, compare, play and design your own maps on iPhone, iPad and Mac. ATLAS • A full-screen world map with 241 countries, territories and regions • Tap any country to see its size, world rank, share of world land and a familiar comparison • 12 map styles, from Political and Original Artwork to Midnight Gold and Nordic Air • Country labels, rivers, lakes and graticule, all offline COMPARE • Line up countries side by side on one shared scale • Overlay shapes and drag them around to see the real difference • Ready-made ideas: The Giants, Greenland vs. DR Congo, Africa’s largest and more QUIZ • Daily Challenge: five mixed questions, the same for everyone each day, with streaks • Find It: tap the country on the map • Which Is Bigger?: two shapes, one true answer • Name the Shape: recognise a country by its outline • Pick a region and level; personal bests are saved MY WORLD • Mark places you have been and places you want to go • See how much of the world you have explored, across six continents • Turn your travels into a poster with one tap MAP STUDIO • Paint countries directly on the map, using your legend categories as brushes • Add a title, subtitle, footer, labels and up to six legend categories • 10 designer palettes plus custom colors • Export PNG or JPEG up to 7200 × 4800 pixels, or a vector PDF that stays sharp at any print size • Keep multiple designs and move editable map files between devices PRIVATE BY DESIGN No account. No ads, in-app purchases, analytics or tracking. Everything stays on your device and works offline. One purchase includes iPhone, iPad and Mac. Cartography: Tom Patterson / Equal Earth. Equal Earth projection by Bojan Šavrič, Tom Patterson and Bernhard Jenny. Made with Natural Earth. Areas are approximate measurements of the map geometry.
